Detailed Description

Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, in which various details of the embodiments of the disclosure are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

The disclosure provides a page rendering method, device, equipment, storage medium and program, which are applied to an application program processing technology and a page display technology in the technical field of computers and can be applied to a page rendering scene to improve page rendering efficiency.

The disclosed embodiments relate to rendering of UI pages, where a UI page typically includes multiple layers, and each layer includes at least one UI element (which may also be referred to as UIBox). For ease of understanding, the structure of the UI page will be described below with reference to fig. 1.

Fig. 1 is a schematic diagram of a UI page provided by an embodiment of the present disclosure. Referring to fig. 1, the UI interface includes a plurality of 3 layers, where layer 1 is located at the bottommost layer, layer 2 is located on layer 1, and layer 3 is located on layer 2. Wherein, the layer 2 further includes a search box, an icon and a navigation bar, which are not shown in fig. 1, located above the layer 1.

The UI element is a two-dimensional rectangular area. Each layer comprises at least one UI unit. For example, the UI elements in layer 1 include a rectangular area occupied by layer 1. The UI unit in layer 2 comprises: the system comprises a rectangular area occupied by a search box, a rectangular area occupied by an electric appliance icon and characters, a rectangular area occupied by a clothing icon and characters, a rectangular area occupied by a payment icon and characters, a rectangular area occupied by a coupon icon and characters, a rectangular area A and a rectangular area occupied by a navigation bar at the lowest edge of a page. The UI elements in layer 3 include rectangular areas B and C.

And occlusion relations exist among UI units in different layers. For example, the UI elements in layer 2 occlude a portion of the UI elements in layer 1. The UI elements in layer 3 (rectangular area B and rectangular area C) occlude a portion of the UI elements in layer 2 (rectangular area a).

In the related art, a browser is usually embedded in an application program, and the UI page is rendered by the browser in a manner of combining HTML, CSS, and Javascript. However, rendering of UI pages is inefficient due to inefficient operation of the browser.

According to the page rendering method, when the first page needs to be rendered, the first page is subjected to layer splitting to obtain the UI units in all layers, the areas which are not shielded in all the UI units are determined, then a plurality of primitives are split in all the areas which are not shielded respectively, and the first page is drawn according to the primitive information of all the primitives. In the process, the rendering of the page can be realized only by processing the layer, the UI unit and the graphics primitive in the page, a browser does not need to be embedded into an application program, and the page rendering efficiency is improved.

The technical solution of the present disclosure is explained in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 2 is a schematic flowchart of a page rendering method according to an embodiment of the present disclosure. Referring to fig. 2, the method may include:

s201, unit information of a plurality of UI units in the first page is acquired.

The execution subject of the embodiment of the present disclosure may be an electronic device, and may also be a page rendering device in the electronic device. The page rendering device may be implemented by software, or may be implemented by a combination of software and hardware.

The first page is a page to be rendered. For example, when a user inputs an operation in the electronic device to request to display the first page, the scheme shown in the embodiment of fig. 2 may be executed to render the first page.

The UI unit refers to a rectangular area in a page, and the rectangular area may be a right-angled rectangular area or a rounded rectangular area. For example, referring to fig. 1, the UI unit corresponding to the electrical icon and the text may be a rectangular area, and the rectangular area a in the layer 2 may be a rectangular area with rounded corners.

The unit information comprises a layer where the UI unit is located and a display position of the UI unit. The display position may be represented by coordinates of the UI unit in the page. Since the UI unit is a rectangular area, the display position of the UI unit can be represented by the upper-left and lower-right coordinates of the UI unit, or can be represented by the upper-right and lower-left coordinates of the UI unit.

The plurality of UI units refer to all UI units included in the first page. Traversal search can be performed in the source code of the first page to obtain the UI unit in each layer, so as to obtain multiple UI units in the first page.

S202, determining the non-shielded areas of the UI units according to the unit information of the UI units.

The unobstructed area of the UI element in each layer can be determined separately. For example, the unoccluded area of the UI unit in the top-most layer may be determined first, then the unoccluded area of the UI unit in the next top-most layer may be determined, and so on until the unoccluded area of the UI unit in the bottom-most layer is determined. Or, the unoccluded area of the UI unit in the layer at the bottom may be determined first, then the unoccluded area of the UI unit in the layer at the second bottom may be determined, and so on, until the area of the UI unit in the layer at the top is determined to be unoccluded.

For the topmost layer, each UI unit in the topmost layer does not have an occluded area, that is, all areas in the topmost UI unit are unoccluded areas.

For a first layer of a non-top layer, when determining an unobstructed area of a first UI unit of the first layer, the unobstructed area of the first UI unit may be determined according to the first layer, a display position of the first UI unit, and a display position of each UI unit in at least one second layer, where the second layer is located on the first layer. For example, suppose that the first page includes 4 layers, which are layer 1, layer 2, layer 3, and layer 4 in sequence from bottom to top. When determining the non-occluded area of the UI unit 1 in the layer 2, the non-occluded area of the UI unit 1 may be determined according to the display position of the UI unit 1 in the layer 2 and the display positions of the UI units in the layers 3 and 4.

In the above process, when determining the non-occluded area of the UI unit in a certain layer, according to whether the layer is the top layer, the non-occluded area of the UI unit in the layer can be determined quickly, so that the efficiency of determining the non-occluded area is high.

Next, the unshielded area of the UI unit will be described with reference to fig. 3.

Fig. 3 is an occlusion diagram of a UI unit provided in the embodiment of the present disclosure. Referring to fig. 3, the image layer includes an image layer 1 and an image layer 2, where the image layer 2 is located above the image layer 1. The layer 1 comprises a UI unit A and a UI unit B, and the layer 2 comprises a UI unit C. The UI unit C is located above the UI unit a and the UI unit B. Referring to fig. 3, the unoccluded area in the UI unit a is an area other than the area 1 in the UI unit a. The unobstructed area in UI element B is the other area in UI element B than area 2.

S203, determining primitive information of a plurality of primitives in the unoccluded areas of the UI units, and drawing the first page according to the primitive information of the primitives.

One or more primitives are included in the UI unit. Primitives are basic elements in a page, e.g., primitives may include line segments, polygons, text, pictures, and so on.

The primitive information is used to describe the primitive, that is, the corresponding primitive can be drawn according to the primitive information. When the primitives are different, the primitive information of the primitives is also different.

For example, the primitive information of the line segment includes at least one of: a start point position, an end point position, a line segment width and a line segment color.

For example, the primitive information of a rectangle includes at least one of: starting point position, ending point position, frame colour, frame width, internal colour and fillet angle.

For example, the primitive information of the polygon includes at least one of: vertex positions of the plurality of vertices, border color, border width, interior color.

For example, the primitive information of the text includes at least one of: text content, font size, color, character position.

For example, the primitive information of the picture includes at least one of: picture, picture position.

After determining that the primitive information of the plurality of primitives is obtained, the primitive information may be sent to a Graphics Processing Unit (GPU) so that the GPU draws a first page according to the primitive information, and after the first page is drawn, the first page may be displayed.

According to the page rendering method provided by the embodiment of the disclosure, when the first page needs to be rendered, unit information of each UI unit in the first page is acquired, an unobstructed area in each UI unit is determined according to the unit information of each UI unit, a plurality of primitives are respectively split in each unobstructed area, and the first page is drawn according to the primitive information of each primitive. In the process, the rendering of the page can be realized only by processing the layer, the UI unit and the graphics primitives in the page, a browser does not need to be embedded in an application program, and the page rendering efficiency is improved.

On the basis of any of the above embodiments, in the process of rendering the first page, it is necessary to determine an unobstructed area of each UI unit in the first page, and the process of determining the unobstructed area of each UI unit is the same.

Fig. 4 is a schematic flowchart of a method for determining an unobstructed area according to an embodiment of the present disclosure. Referring to fig. 4, the method may include:

s401, determining a first layer where the first UI unit is located.

S402, judging whether the first layer is the top layer.

If yes, go to S403.

If not, go to S404.

The layer identifier and the total layer number of the first layer can be obtained, and whether the first layer is the top layer is judged according to the identifier and the total layer number of the first layer.

For example, if the layer identifier of the bottommost layer is the smallest and the layer identifier of the topmost layer is the largest, it may be determined whether the first layer identifier is the same as the total number of layers, if so, it is determined that the first layer is the top layer, and if not, it is determined that the first layer is not the top layer.

And S403, determining all areas of the first UI unit as the non-shielded areas of the first UI unit.

If the first layer is the topmost layer, no UI unit is located on the first layer, that is, no UI unit is located on the first UI unit, and then the entire area of the first UI unit may be determined as the non-occluded area of the first UI unit.

S404, judging whether the display position of the UI unit in the second layer and the display position of the first UI unit have an overlapping area or not according to the display position of the first UI unit and the display position of each UI unit in at least one second layer.

Wherein the second layer is located above the first layer.

If yes, go to S405.

If not, go to step S403.

If the first layer is a non-top layer, there may be a UI unit located on the first UI unit, or there may be no UI unit located on the first UI unit, so that an unobstructed area of the first UI unit needs to be determined according to a display position of the first UI unit and a display position of each UI unit in the second layer.

The display positions of the UI units in the second layer may be obtained, and if there is an overlapping area between the display position where no UI unit exists in the second layer and the display position of the first UI unit, the entire area of the first UI unit may be determined as an unobstructed area of the first UI unit. If there is an overlapping area between the display position of the UI unit and the display position of the first UI unit in the second layer, it is necessary to further determine an unobstructed area of the first UI unit according to S405-S406.

In the above process, when it is determined that there is an overlapping area between the display position where the UI unit does not exist in the second layer and the display position of the first UI unit, the whole area of the first UI unit in the non-occluded area of the first UI unit may be directly determined, so that the efficiency of determining the non-occluded area of the first UI unit is higher.

And the display position of the second UI unit and the display position of the first UI unit have an overlapped area.

In the embodiment shown in fig. 4, when determining an unobstructed area of a first UI unit in a first layer, it may be determined whether the first layer is a top layer, and when the first layer is the top layer, it may be directly determined that the unobstructed area of the first UI unit is all areas of the first UI unit, so that the efficiency of determining the unobstructed area of the first UI unit is higher. When the first layer is a non-top layer, whether a UI unit and a first UI unit overlap in a second layer located above the first layer may be determined again, if not, the non-occluded area of the first UI unit may be directly determined to be all the area of the first UI unit, and if yes, the non-occluded area of the first UI unit may be further determined. In the above process, the unobstructed area of the first UI unit is determined through multiple stages, so that the efficiency of determining the unobstructed area of the first UI unit is high.

On the basis of any one of the above embodiments, the page rendering method shown in the embodiment of the present disclosure is further described in detail below with reference to fig. 5.
